O allele 60 + 60+30 = 150
o allele
30 + 10+10 = 50
O allele frequency = 150/200 = 0.75
Thus, the O allele frequency is 3/4 or 0.75
o allele frequency = 50/200 = 0.25
The o allele frequency is 1/4 or 0.25
Answer:
Troposphere is the lowest layer of Earth’s atmosphere that has undergone a large increase in temperature due to the presence of greenhouse gases.
Explanation:
Troposphere (0 to 12 km) where we live is the lowest layer of earth's atmosphere, which is closest to the earth's surface contains half of the atmosphere. Here most clouds are found and almost all weather occurs. Atmosphere contains approximately 78% of nitrogen , 21% of oxygen and 0.9% of argon. Gases like carbon dioxide, nitrous oxides, methane, ozone and the water vapor constitutes the rest of the atmosphere. Many small particles called aerosols are also there which include dust, spores, pollen, volcanic ash, smoke etc.The greenhouse effect is a natural phenomenon that keeps the temperature on the earth suitable for supporting life. The greenhouse gases includes both natural and man-made gases like carbon dioxide
, methane, nitrous oxide, chlorofluorocarbons, hydrochlorofluorocarbons, ozone, water vapour. They absorb radiation in the atmosphere and create the green house effect. The thermal infrared radiation emitted by the Earth’s surface and the atmosphere is absorbed by greenhouse gases. They trap heat within the surface-troposphere system preventing it from escaping back into space. This is called the greenhouse effect, which increases the temperature of the lower atmosphere.The increase in the atmospheric concentrations of greenhouse gases due to human activity has caused an increase in the natural greenhouse effect. As a result, the atmosphere is trapping too much heat which increases the temperature of the Earth.
Lysosomes are vesicles that are formed by the Golgi apparatus. They contain powerful enzymes that could break down (digest) the cell. Lysosomes break down harmful cell products, waste materials, and cellular debris and then force them out of the cell.
They interact with light to absorb only certain wavelengths, pigments are useful to plants and other Autotrophs, organisms which makes their own food using photosynthesis. in plants,algae,and Cyanobacteria, pigments are the means by which energy of sunlight is captured by photosynthesis.
